Nintendo 64 Release Guide

Converting MIDI files into a playable music Nintendo 64 (N64) cartridge involves several steps, including preparing your MIDI files, converting them into a format compatible with the N64’s audio system, assembling an N64 ROM, and finally flashing the ROM onto a physical cartridge. This process is more complex than for earlier consoles due to the N64’s advanced architecture and the scarcity of development tools. Below is a detailed, step-by-step guide to help you through the process.


Prerequisites

Before you begin, ensure you have the following:

Note: Developing for the N64 is complex due to proprietary hardware and limited documentation. The community-driven tools may have limitations.


Step 1: Prepare Your MIDI File

1. Simplify the MIDI File

The N64’s audio system can handle complex audio, but to ensure compatibility:

Recommended MIDI Editors:


Step 2: Install N64 Development Tools

1. Install MIPS Compiler Toolchain

2. Install libdragon

3. Set Up Development Environment


Step 3: Convert MIDI Files to N64-Compatible Format

1. Understand N64 Audio Format

2. Use Sequencer Tools

3. Convert MIDI to N64 Sequence


Step 4: Prepare Audio Samples

1. Convert Instrument Samples

2. Convert Samples to N64 Format


Step 5: Integrate Audio Data into N64 ROM

1. Create a libdragon Project

2. Place Audio Files

3. Write the Main Program

4. Audio Playback Implementation


Step 6: Write a Makefile


Step 7: Compile the N64 ROM

1. Run the Build Command

2. Troubleshooting


Step 8: Test the ROM in an Emulator

1. Choose an Emulator

2. Load and Test the ROM


Step 9: Flash the ROM onto an N64 Cartridge

1. Obtain a Flash Cartridge

2. Prepare the ROM

3. Transfer the ROM


Step 10: Play the Cartridge on an N64 Console

1. Insert the Cartridge

Additional Tips


Summary

By following these steps, you can convert MIDI files into a playable music N64 cartridge:

  1. Prepare and optimize your MIDI file to suit the N64’s capabilities.
  2. Install N64 development tools, such as libdragon and the MIPS compiler toolchain.
  3. Convert the MIDI file into an N64-compatible sequence using tools like Seq64.
  4. Prepare audio samples and convert them into a sound bank for the N64.
  5. Integrate the audio data into an N64 ROM by writing a program that utilizes libdragon.
  6. Compile your ROM using appropriate build tools and Makefiles.
  7. Test your ROM in an emulator to verify functionality and troubleshoot issues.
  8. Flash the ROM onto a physical cartridge using hardware like the EverDrive 64.
  9. Play the cartridge on an actual N64 console to enjoy your custom music.

This process provides a deep dive into N64 development and allows you to experience custom music on original hardware.
